Technical Field
[0001] The utility model relates to the technical field of scaffolds, in particular to a hook pedal self-locking device for a scaffold. Background Art
[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. It can be divided into external scaffolding and internal scaffolding according to the location of the erection; it can be divided into wooden scaffolding, bamboo scaffolding and steel pipe scaffolding according to different materials; it can be divided into pole scaffolding, bridge scaffolding, portal scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding and climbing scaffolding according to the structural form. Hook pedals are usually used in the use of scaffolding to assist in the construction of the scaffolding.
[0003] During use, the existing hook pedal for scaffolding is usually hung directly on the scaffolding. The direct hanging method lacks a certain self-locking structure, which makes the hook pedal at risk of falling off during use, which is not conducive to ensuring the safety of personnel and materials on the scaffolding, as well as the safety of personnel passing near the scaffolding. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a self-locking device for a hook pedal for a scaffold, so as to solve the technical problem that the existing hook pedal for scaffold has certain safety hazards during use and its safety of use needs to be further improved.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-locking device for a hook pedal for a scaffold, comprising a device body, the device body comprising a bottom main board and a movable buckle plate, a reset mechanism is arranged on the bottom main board and the movable buckle plate, the reset mechanism comprises a first fixed column and a second fixed column, a third fixed column is arranged on the top of the movable buckle plate, and a reset spring is arranged on the third fixed column.
[0006] By adopting the above technical solution, the third fixed column is used to drive the recovery of the movable buckle plate, and the corresponding parts of the scaffolding are clamped into the device body at both ends of the hook pedal. When the movable buckle plate is recovered, the reset spring will be squeezed to shrink smoothly. When the third fixed column is released, the reset spring will reset to achieve self-locking, and then the corresponding parts of the scaffolding will be clamped on the bottom main board and the movable buckle plate.
[0007] Furthermore, the first fixing column and the second fixing column are both welded to the bottom main board.
[0008] By adopting the above technical solution, the first fixing column and the second fixing column are fixed on the bottom main board, so that the auxiliary reset mechanism can normally hang the hook pedal on the scaffolding and then self-lock.
[0009] Furthermore, the third fixing column is welded to the movable buckle plate, and the movable buckle plate is rotatably connected to the bottom main board.
[0010] By adopting the above technical solution, the third fixed column is fixed to the movable buckle plate. When force is applied to the third fixed column, the movable buckle plate fixedly connected to it is rotated under the force and rotates along the bottom main board so that the corresponding part of the scaffolding can be clamped into the device body.
[0011] Furthermore, the return spring is a helical structure.
[0012] By adopting the above technical solution, the reset spring can be squeezed and contracted during the recovery of the movable buckle plate. When the movable buckle plate is no longer subjected to force, the reset spring can smoothly drive the movable buckle plate to reset in the opposite direction to achieve self-locking.
[0013] Furthermore, the two ends of the return spring are respectively provided with a first end and a second end, a hook ring is provided on one side of the second fixing column, and a circular through hole is provided on the third fixing column.
[0014] By adopting the above technical solution, the reset spring is temporarily fixed on the second fixing column and the third fixing column through the first end, the second end, the hook and the circular through hole. When the reset spring is continuously consumed during long-term use and the reset ability is weakened, affecting the use effect, the reset spring can be removed and replaced.
[0015] Furthermore, the first end and the second end are both fixedly connected to a return spring.
[0016] By adopting the above technical solution, the first end and the second end are respectively fixed to the reset spring, and the reset spring fixedly connected to the first end and the second end can be fixed to the corresponding position of the device body by fixing the first end and the second end.
[0017] Furthermore, the first end is buckled on the hook ring, and the second end is buckled on the circular through hole.
[0018] By adopting the above technical solution, the first end and the second end are temporarily fixed to the hook ring and the circular through hole by buckling, so that the return spring fixedly connected to the first end and the second end is temporarily fixed to the second fixing column and the third fixing column.
[0019] Furthermore, the hook ring is in a semi-annular structure, and the hook ring is fixedly connected to the second fixing column.
[0020] By adopting the above technical solution, the hook ring with a semi-annular structure facilitates the smooth buckling of the first end, and smoothly fixes one end of the return spring on the hook ring.
[0021] In summary, the utility model mainly has the following beneficial effects:
[0022] 1. The utility model sets a first fixed column, a second fixed column, a third fixed column and a reset spring. After applying force to the third fixed column, the movable buckle plate can be driven to be recovered and the reset spring can be squeezed. When the device body assists the hook pedal to be hung on the scaffold, after the force applied to the third fixed column is cancelled, the reset spring resets itself to achieve a self-locking effect, thereby ensuring that the hook pedal is not easy to fall off from the corresponding position of the scaffold, thereby greatly improving the safety of the entire movable frame.
[0023] 2. The utility model provides a first end, a second end, a hook and a circular through hole, so that the first end and the second end can be used to buckle the reset spring on the hook and the circular through hole respectively, and then the reset spring can be temporarily fixed on the second fixing column and the third fixing column.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0030] The following describes an embodiment of the utility model based on its overall structure.
[0031] Embodiment 1:
[0032] A self-locking device for a hook pedal of a scaffold, such as Figure 1-Figure 4 As shown, it includes a device body 1, which includes a bottom main board 11 and a movable buckle plate 12. A reset mechanism 2 is arranged on the bottom main board 11 and the movable buckle plate 12. The reset mechanism 2 includes a first fixed column 21 and a second fixed column 22. A third fixed column 23 is arranged on the top of the movable buckle plate 12. A reset spring 24 is arranged on the third fixed column 23. The third fixed column 23 is used to drive the recovery of the movable buckle plate 12, and the corresponding part of the scaffolding is clamped into the device body 1 at both ends of the hook pedal. When the movable buckle plate 12 is recovered, the reset spring 24 will be squeezed to shrink smoothly. When the third fixed column 23 is released, the reset spring 24 is reset to achieve self-locking, and then the corresponding part of the scaffolding is clamped between the bottom main board 11 and the movable buckle plate 12. In this process, the first fixed column 21 and the second fixed column 22, as well as the corresponding through grooves on the movable buckle plate 12 restrict the first fixed column 21 and the second fixed column 22, so that the movable buckle plate 12 can only be recovered inward and cannot be opened in the reverse direction, further ensuring the self-locking effect.
[0033] See also Figure 1 , Figure 2 The first fixing column 21 and the second fixing column 22 are both welded to the bottom main board 11. The first fixing column 21 and the second fixing column 22 are fixed to the bottom main board 11 so that the auxiliary reset mechanism 2 can normally hang the hook pedal on the scaffolding and then self-lock. At the same time, the first fixing column 21 and the second fixing column 22 are connected to the bottom main board 11 by welding to ensure better connection performance and fixing effect.
[0034] See also Figure 1 , Figure 2 The third fixed column 23 is welded to the movable buckle plate 12, and the movable buckle plate 12 is rotatably connected to the bottom main board 11 to fix the third fixed column 23 and the movable buckle plate 12. When force is applied to the third fixed column 23, the movable buckle plate 12 fixedly connected thereto is rotated under the force and rotates along the bottom main board 11 so that the corresponding part of the scaffolding can be stuck into the device body 1. The third fixed column 23 and the movable buckle plate 12 are fixed by welding, so that the third fixed column 23 can be tightly fixed on the movable buckle plate 12 to ensure the stability of the connection between the two.
[0035] See also Figure 1 , Figure 2 The return spring 24 has a spiral structure. The return spring 24 can be squeezed and contracted during the recovery of the movable buckle plate 12. When the movable buckle plate 12 is no longer subjected to force, the return spring 24 can smoothly drive the movable buckle plate 12 to reset in the opposite direction to achieve self-locking. The return spring 24 adopts a spiral structure, so that the return spring 24 has a higher elastic coefficient, can withstand larger deformation, and has good elastic recovery ability.
[0036] Embodiment 2:
[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The two ends of the return spring 24 are respectively provided with a first end 25 and a second end 26, a hook ring 27 is provided on one side of the second fixing column 22, and a circular through hole 28 is provided on the third fixing column 23, so that the return spring 24 is temporarily fixed on the second fixing column 22 and the third fixing column 23 through the first end 25, the second end 26, the hook ring 27 and the circular through hole 28. When the return spring 24 is continuously consumed during long-term use and the return ability is weakened, affecting the use effect, the return spring 24 can be removed and replaced to ensure that the entire device body 1 can still be used by replacing a new return spring 24 after the return spring 24 is damaged.
[0038] See also Figure 1 , Figure 2 The first end 25 and the second end 26 are both fixedly connected to the return spring 24. The first end 25 and the second end 26 are respectively fixed to the return spring 24. The return spring 24 fixedly connected to the first end 25 and the second end 26 can be fixed to the corresponding position of the device body 1. After the return spring 24 is fixed to the corresponding position of the device body 1, it can shrink under the action of external force. When the external force is cancelled, the corresponding part is driven to reset to achieve self-locking.
[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The first end 25 is buckled on the hook ring 27, and the second end 26 is buckled on the circular through hole 28. The first end 25 and the second end 26 are temporarily fixed to the hook ring 27 and the circular through hole 28 by buckling, so that the return spring 24 fixedly connected to the first end 25 and the second end 26 is temporarily fixed on the second fixing column 22 and the third fixing column 23, which can not only connect the second fixing column 22 and the third fixing column 23 during use to play the role of contraction and reset self-locking, but also can remove the return spring 24 when it is damaged and replace it.
[0040] See also Figure 1 , Figure 2 , Figure 4The hook ring 27 has a semi-annular structure and is fixedly connected to the second fixing column 22. The semi-annular structure of the hook ring 27 facilitates the smooth buckling of the first end 25, and one end of the reset spring 24 is smoothly fixed on the hook ring 27. The second fixing column 22 provides support for the hook ring 27, fixes the hook ring 27 in the corresponding position, and ensures that the hook ring 27 functions stably.
[0041] The implementation principle of the utility model is as follows: first, the scaffold is built, and when the hook pedal needs to be placed, force is applied to the third fixing columns 23 of the device body 1 on both sides of the hook pedal, driving the movable buckle plate 12 fixedly connected to the third fixing columns 23 to rotate along the bottom main board 11, and at this time the reset spring 24 is squeezed and contracted; secondly, when the movable buckle plate 12 moves to a suitable position, the corresponding part of the scaffold is clamped in the device body 1, and the third fixing column 23 is released. Under the action of the reset spring 24, the movable buckle plate 12 is smoothly reset, completing the self- Lock; at the same time, due to the limiting effect of the first fixed column 21 and the second fixed column 22, the movable buckle plate 12 cannot be rotated in the opposite direction along the bottom main board 11 to open, thereby ensuring the safety of the device body 1 during use; finally, when the hook pedal is used up and disassembled, it is only necessary to apply force to the third fixed column 23 again to retract the movable buckle plate 12, and squeeze the return spring 24 again to make it shrink smoothly, move the hook pedal upward to separate it from the scaffolding, and then release the third fixed column 23 again, and the return spring 24 will reset the device body 1 again, and the disassembly is completed.
[0042] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
